Motivated to improve their defense and get Wilin Rosario's bat in the lineup more often, the Rockies are pursuing free agent catcher Carlos Ruiz, according to multiple major league sources.

The Rockies also face a decision Monday on whether to pick up reliever Matt Belisle's $4.25-million option.

Rockies owner Dick Monfort has identified landing an impact bat as a priority this winter. Ruiz would not be expected to help on offense as much as on defense, where Rosario has struggled. Colorado has also expressed interest in free agent catcher Brian McCann, but he could be the highest-paid player on the market, leaving the veteran Ruiz a more realistic target.
